Python学习之路：通过socket实现处理多个连接

-----客户端

#客户端
import socket

client = socket.socket()#相当于声明socket类型，同时生成socket连接对象
client.connect(('localhost',6969))

while True:
    msg = input(">>:").strip()
    #client.send(b"Hello World!")
    client.send(msg.encode("UTF-8"))
    data = client.recv(1024)
    #print("recv:",data)
    print("recv:",data.decode())

client.close()

------服务端

#服务器端
import socket

server = socket.socket()
server.bind(("localhost",6969))#绑定要监听的端口
server.listen()#监听

print("我要开始等电话了")

while True:
    conn,addr = server.accept()#等电话打进来
    print(conn,addr)

    print("电话来了")
    while True:
        data = conn.recv(1024)
        print("recv:",data)
        if not data:
            print("client has lost...")
            break
        conn.send(data.upper())

server.close()
